Superfinishing

The Isotropic Super Finishing (ISF®) treatment is an industry-leading process that uses mass finishing equipment with non-hazardous chemical accelerants to surface treat ring and pinion sets. Testing shows that treated gears have proven to improve performance of racecars and are used by NASCAR and IndyCar teams!

Our Superfinishing Capabilities

Our Lightning® Seriesgears undergo a unique treatment known as Isotropic Superfinishing (ISF®). This superfinish treatment is completed in-house and is available for all our street and competition ring and pinion gears.

The superfinish process produces not only an outstanding highly-polished look, it also generates a nondirectional low RA surface, which is the measurement of surface finish, or smoothness, of a part. Produced with mass finishing equipment in conjunction with chemical accelerants, the ISF process is nonhazardous and environmentally friendly.
